© Paula Sola La Serna & José J. Chambó Bris
Comet 174P/Echeclus photographed on December 15th, 2017, during its last outburst. Discovered in 2000 it was classified as an Centaur type asteroid circulating between the orbits of Uranus and Jupiter, but years later it showed cometary activity with outbursts in 2006, 2011, 2016 and the present in 2017.
Besides of brightness increase from 17.5 to 13.5 magnitude, the most remarkable has been the increase in coma size from 10 to 40 arcseconds. Thanks to resolution of Telescope IAC-80 in this image the internal structure of coma can be seen, wich shows jets departing from nucleus and a dark shape toward South.
